This mod will make it so you can use double AA batteries with your DP5V Dosimeter, you will not need to use the soviet KR1 Batteries. For best results add adhesive underneath the printed part so it will stick and reduce vibrations and the chances of it falling out. Also, make sure to wrap the batteries in tinfoil for better results. Make sure you put the batteries in the right way to improve the chances of it working. If this does not work this may mean that the capacitors inside of your dosimeter may not be working and you will need to replace them, over time they will wear out.
